ANTI-RAIL-CREEPING DEVICE.

To all whom it may concern.'

Be it known that l, .Toux Wonen, a citizen of the United States of America, residing' at Cleveland, in the county of Cuyahoga and State ot' Ohio, have invented certain new andnset'ul Improvements in A\ntilail (,lreeping' Devices; and l hereby declare the tollowingto be a full, clear, and exact de- Scriptionvofythe invention, such as will enable others skilled in the art to which it pertains tomake and use the same.

This invention relates to anti-rail-creeping devices ot' the type which arc designed to prevent the creeping' ot' the rails in the direct iony ot' their length due to the action ot' the wheelsof passing' trains.

Tile object'ofthis invention is the provision ofan anti-rail-creeping device which is simple and cheap in construction but etfective in operation7 which can be very easily attached to the rail or removed theret'ronnand which will not be loosened by vibration.

The invention contemplates the use ot' a member whichwhen the device is in place is underneath the rail and is held from movement. with the rail by oueo't' the ties and is provided with toothed members which `f vrip or engage the rail flanges in a manner such that any creeping' tendency ot' the rail will cause said meml'iers to grip the rail all the more tightly.

4ln the preferred embodiment ot my invention the member to which the links are pivoled has a portion which extends beneath the flange ot' the rail longitudinally thereo't' and a portion which is curved and extends outwardly beyond the rail and at substantially right-angles thereto. This outwardly or laterally extending end of the member passes through a block which is heldfrom movement with the rail by engagementwith one of the ties and which is provided with a slot adapted to receive the flange of the rail, the rear Wall of the slot having teeth which ,tightly grip the rail.A

(,)ne ofthe links which are connected to this member is pivoted to the end of the member and extendsoutwardly in one direction, and the other link is pivoted to the member intermediate its ends or atta distance from the pivoted` connection `of .the first mentioned link and extends loutwardly in the opposite direction, Said links having at their outer Specification of Letters Patent.

ends toothed canuning' members which are pivoted to the links and are caused to tightl)r grip the opposite edges of the rail flanges; when said block is clamped against the flanges ot the rail by a wedge or spike.

'lhe invention maybe tui-ther briefly summarized as consisting' in certain novel details o't constructimi and combination and arrangements of vparts which will be described in the slwcitieation and set t'orth in the appended claims.

For au nlulerstanding ot my invention reference is had to the accompanying sheet ot' dln-lwiue's wherein-- Figure l- .shows a plan view of portions ol a tie and rail` the latter beine' equipped with one o'lt my improved anti-rail-creepinp; devices. l `i; j, Q is an enlarged transverse secticn substantially along the line 2-2 of Fig'. 1 looking' in the direction indicated by the arrow.

.Referring now to Figs. 1 and 2 ot: the drawingl'sI 1t) represents one ot' thc rails ot' a track and ll a portion of one otl the ties, the rail beine' designed to he .secured to the tie in the usual or in any desired manner. My improved anticreepilmlr device is designed For the purpose ot' preventing the creeping' of the rail due to the action ot the wheels ot' a passingT train. and in this case prevents the creeping or lengthwise movement of the rail in the direction indicated b v the arrow in the upper portion of Fig. 1. The anticreeping device includes an arm or member .19 which. as shown in the drawings. is underneath the flange o'l the rail and has a portion which extends longitudinally of the rail and at one end is curved outwardly or laterally beyond the rail and atI right angles thereto as shown at 13. The laterally projecting portion 13 of the arm 12 passes throng-rh an openingv in a block 14 which is provided with a slot. 15 adapted to receive the flange of the rail `and is designed to be clamped tightlv `against' the latter by a wedge-shaped member 1G adapted to be drivenptightly into'an aperturenear the outer end of the portion 13 of the arm 12, The lower portion 14 of the block 14;

$5 looking in the direc.

is inclined, as shown, so that the lower end 16SL of the wedge 16 is bent and its accidental removal prevented or rendered improbable. Thel rear wall of the slotted portion of the block isprovided with a series of teeth 17 which grip the flange of the rail when said block is clamped against the latter. Pivotally secured to the arm 12, in this case,

i by r1vets 18, are two links or arms 19 and 20 which extend outwardly from said arm 12 in opposite directions and are designed to engage opposite sides or edges of the rail flange, as will be explained. The link or arm 20 is in this case secured to the arm 12 near the center thereof or some distance from the point of attachment of the link 19. The inner ends of the links 19 and 20 are secured to the upper face of the arm 12 so that they will lie against the bottom or lower face of the rail flange, the upper heads of the rivets 18 being received in countersunk holes in ythe links. The links 19 and 2O extend outwardly or laterally beyond the edges of the rail flange for a suit-able distance and are bent or doubled inwardly over the rail flange as shown at 2l and 22 in the drawings, the upper doubled portions of the links being substantially parallel to the lower main portions thereof. Each of these pivoted links is provided lat its outer or free end between the parallel facesl formed by doubling the outer end inward7 with a toothed camming member 23 which is substantially semi-circular, its inner edge, however, being slightly curved or rounded and having a series olf teeth 24 which are adapted to grip' or bite the edges of the rail flange. These toothed camming members 23 are held in position by rivets 25 which pass entirely through the outer ends of these links. In order that the camming' members 23 may be' readily removed or placed in position in the links, they are provided with open slots which receive the shanks of the rivets and which permit these members to be slipped out of place or placed in position when the anti-rail-creeping device is not attached to the rail.

It will be seen from the construction above described that when the device is first laced in position t? be secured to the ra1l, the toothed cammmg members 23 will not tightly bite the rail flange, but when the outer end 13 of the arm 12 is drawn through the opening in the block 14 thetoothed portions of these camming members will be caused to engage the edges ofthe rail flange and when the block 14 is clamped against the rail by driving in the wedge 16, the pivoted point of each of the links is drawn away from the edge or flange of the rail which is adapted to be engaged by the correspondingtoothed camining members 23, kso that when the device is being clamped in position this arm 12 acts somewhat as 'a lever todraw vand 14.

the inner or pivoted ends of the two links simultaneously in opposite directions until the parts assume the position shown in Fig. 1. When the wedge 16 is driven in place the teeth of the camming members 23 and the block 14 will* tightly grip the edges of the rail flange. If now the rail should tend to creep in the direction indicated by the arrow, the block 14 and the arm 12 cannot move with the rail inasmuch as the block 14 engages the tie 11. Any creeping tendency, however, will tend to cause the links to swing on their pivotal centers and to cause the outer ends of the links and the toothed camming members 23 to move with the rail inasmuch as the teeth are in firm `cngagement therewith. This would cause the camming members to rock slightly and would increase the gripping action of the camming members upon the rail. Consequentlyin view of this @imming and gripping action of the members 23 there will be practically no lengthwise movement of the rail.

In Figs. 3 and 4 I have shown a modified form of my construct-ion in which 10 represents the rails of a track, and 1 1 a portion of one of the ties, the rails beine' 'fastened to the ties in the usual manner. My modified device consists of a plate 12 which passes under the rail and transversely thereof so as to extend laterally on `each side, as at 13 The end of the portion 14: is turned or folded upwardlyl and over, as shown at 1,5. Pivotally secured between the laterally extending portion 14 and the portion 15 is a camming member 16. The inner face ofsaid camming member 16 is provided witha series of teeth 17 which are adapted to grip the edge of the rail flange. The camming member 16 is held in position by a rivet 18 which passes entirely through the plate 12. The laterally extending portion 13 of the plate 12 passes through an opening 19 in a block 20 which is provided with a slot 21 adapted to receive the flange of the rail and isldesigned'to be clamped tightly against the latter by a wedge-shaped member 22 which is driven tightly into an aperture 2 near the outer edge of the laterally extending portion 13 of the plate 12. rIhe lower portion 2()2 of the block 20 is inclined so that the lower end 21 of the wedge 22 will be bent and its accidental removal prevented. The rear wall of the slotted portion of the block 20 is provided with a series of teeth 25 which grip the flange ofthe rail when the said block is clamped against the latter. When the dev-ice assembled on the rail it is arranged so one end of the block 20 will bear against the side of the tie. It will therefore be seen from the above described construction that when the device is tightl clamped in position any tendency of the rail to creep would cause the cammng member to rock slightly thus causing the device to preventing the creeping ot' the r'ail, said de l `vice comprising an arin beneath the rail flaiige and held `troni movement in the direction of' the length of' the rail, a pair ot links'l pivoted to said arm at points spaeed from one another lengthwise ot the arm, said links extendingl laterally of said arm and engaging opposite sides olE the rail flange, the outer portions of said links having pivoted thereto members provided with teeth whieh engage or grip opposite edges of the rail flange.
